Thirty-five patients who had rheumatoid arthritis of both knees, but no gross deformity of the patella, had bilateral total knee arthroplasty. In each patient, one knee had a patellar replacement and the other did not. All of the patients were followed for a minimum of two years. The results were the same in both knees in terms of relief of pain and improvement in function, arc of motion, and muscle power. Although no complications that were related to patellar replacement developed in these patients, routine replacement of patellae that have little or no deformity does not seem advisable.
35例双膝患有类风湿性关节炎但髌骨无明显畸形的患者接受了双侧全膝关节置换术。在每位患者中，一侧膝关节进行了髌骨置换，另一侧未进行。所有患者均接受了至少两年的随访。在缓解疼痛、改善功能、活动弧度和肌肉力量方面，双膝的结果相同。尽管这些患者未出现与髌骨置换相关的并发症，但对于几乎没有或没有畸形的髌骨进行常规置换似乎并不可取。
